PATENT LOCK-HINGE.

SPECIFICATION forming part of Letters Patent N 0. 726,870, dated May 5, 1903.

Application filed July 2,1901. 'Serial No. 66,928. (No model.)

To all whom it may concern.-

Be it known that I, EMIL GORNBERG, a citi zen of the United States, residingat Gardner, in the county of Worcester and- Commonwealth of Massachusetts, have invented a new and useful Improvement in L0ck-Hinges,'of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 represents in perspective view a window-shutter with myimproved shutterfastener attached thereto. Fig. 2is a front elevation of the fastening device removed from the shutter. Figs. 3 and 4 represent top views of portions of the fastener.

Similar reference letters refer to similar parts in the different views.

My invention relates to a shutter-fastener combined with the hinge of the shutter for the purpose of locking the shutter in its opened or closed position; and it consists in providing the leaves of the shutter-hinge with projecting notched wings adapted to engage a bracket attached to the building, said wings having beveled ends adapted to slide over the bracket as the shutter is opened or closed, and thereby cause the shutter to be automatically fastened by the operation of opening or closing.

Referring to the drawings, A, Fig. 1, denotes a window-shutter provided with hinges which comprise the leaves B at right angles to each other, which are attached to the shutter by screws B, and a barrel B inclosing the pintles C O, which are supported upon the brackets D, attached to the side of the bracket, the plate having a notched wing 10- building. The leaves 13 are provided with wings E E, projecting at right angles to said leaves and having notches F F and beveled lower-ends G G. The bracket D consists of a bar H parallel with the side of the building I and having the legs J J, which are attached to the building, the pintles C 0 being sup ported at the corner formed by the bar H and leg J, which are at right angles to each other and contribute the two members of the bracket which are engaged by the notched wings E E. Then the shutter is closed in the position shown in Fig. 1, the beveled end G of the wing E slides over the leg J of the bracket, thereby slightly lifting the shutter, which falls into position as the shutter is fully closed, causing the notch F to engage allow the projection K to pass through the barrel when the shutter is midway between its opened or closed position; butin allother positions the projection K is arranged to extend over the top of the barrel, as shown in Fig. 3, and prevent the barrel from being entirely lifted off the pintle.

The upper and lower hinges of the shutter are duplicates of each other, thereby locking the shutter in position near the upperancl lower ends. The bracket upon which the shutter is hinged is provided with two points of attachment by the legs J J, and the locking-wings E E are formed by turning over the edges of the leaves B, allowing the hinges to be stamped from sheet metal, and the necessity of looking or fastening devices on the window-stool is obviated.

What 'I claim as my invention, and desire to secure by Letters Patent, is-

1.- A lock-hinge comprising a plate and a cated away from the barrel of the hinge, the wing having a beveled end to ride up on the bracket, the bracket comprising two members at an angle to each other, one ofwhich is arranged to be engaged by the notched wing to lock the movable device to which the hinge is attached, in position.

2. A lock-hinge comprising two. parts, one of which is a bracket, and the other a .pair of integral leaves disposed at an angle to each other whereby to embrace two edges of the hinged device, and notched wings projecting outwardly from the leaves constructed to ride said wings beveled on one edge and notched up upon and engage the bracket in either of to ride up upon and lock,t0 the bracket. the extreme positions of the hinged device. Dated this 1st day of June, 1901.

3. Alock-hingecomprisingabracket apin- 7 1 tie and a sheet-metal plate bent at the center EMIL OORNLERG to form a barrel and two leaves disposed at Witnesses: an angle to each other and the ends of the EDWARD G. WVATKINS, leaves bent outwardly in the form of wings, THATOHER B. DUNN.
